Question 1 of 35
1. Question
Consider the following pairs with respect to the main mineral constituents of the interior of the Earth.
Layers of Earth Constituents
- The Continental crust – Silica and Magnesium
- The Oceanic crust – Silica and Alumina
- The Core – Nickel, and Iron
How many of the pairs given above are correctly matched?
Correct
Solution (a)
Statement 1 Statement 2 Statement 3 Incorrect Incorrect correct The Earth is made up of several concentric layers with one inside another. The uppermost layer over the Earth’s surface is called the crust. It is the thinnest of all the layers. The main mineral constituents of the continental mass are silica and alumina. It is thus called sial (si-silica and al-alumina).
The oceanic crust mainly consists of silica and magnesium; it is therefore called sima (si-silica and ma-magnesium) The innermost layer is the core with a radius of about 3500 km. It is mainly made up of nickel and iron and is called NiFe Incorrect

Question 2 of 35
2. Question
Consider the following statements regarding Earth’s Crust
- The outermost solid part of the earth is called the crust, which predominantly consists of Peridotite.
- Oceanic crust is thinner as compared to continental crust.
- The upper part of the crust consists of Basaltic rocks and the lower part consists of Granitic rocks.
- The weaker zone of the earth’s crust is called Asthenosphere.
How many of the above statements are correct?
Correct
Solution (a)
Statement 1 Statement 2 Statement 3 Statement 4 Incorrect Correct Incorrect Incorrect Peridotite is a dark-colored igneous rock consisting mostly of olivine and pyroxene. It is an important rock type because the Earth’s mantle is predominantly composed of it. The crust is the outermost solid part of the earth. It is brittle in nature. The thickness of the crust varies under the oceanic and continental areas. The oceanic crust is thinner as compared to the continental crust. The thickness of the oceanic crust is 5km whereas that of the continental crust is around 30 km. The upper part of the crust consists of granite rocks and forms the continents. Its main minerals constitute are silica and alumina. The lower part of the crust consists of basaltic rocks forming the ocean floors, comprising mainly silica, iron, and magnesium. The Asthenosphere is a weak zone of Earth’s Mantle and not of the Earth’s crust. Its upper layer of the earth’s mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection, is thought to occur. Incorrect

3. Question
Consider the following statements concerning Earthquake waves:
- P-waves move faster but S-waves are the first to arrive at the surface.
- P-waves can travel only through gaseous and liquid materials.
- S-waves can travel only through solid materials.
- Surface waves are considered to be the most damaging waves.
How many of the above statements are correct?
Correct
Solution (b)
Statement 1 Statement 2 Statement 3 Statement 4 Incorrect Incorrect Correct Correct P-waves move faster than S-waves and are the first to arrive at the surface. These waves occur at a high frequency. P Waves can travel in all mediums. The velocity of P waves in Solids > Liquids >Gases. Their velocity depends on the shear strength or elasticity of the material.
A secondary wave cannot pass through liquids or gases. These waves are high frequency waves.
They travel at varying velocities (proportional to shear strength) through the solid part of the Earth’s crust, mantle.
The Surface waves are the most destructive. They are recorded last on the seismograph. Incorrect

4. Question
Consider the following statements regarding the geomorphic forces acting on the landforms:
- For the endogenic process, the energy is generated by rotational and tidal friction only.
- The process of diastrophism and volcanism come under exogenic forces.
- Temperature and precipitation control the various exogenic forces.
How many of the above statements are correct?
Correct
Solution (a)
Statement 1 Statement 2 Statement 3 Incorrect Incorrect Correct The energy emanating from within the earth is the main force behind endogenic geomorphic processes.
This energy is mostly generated by radioactivity, rotational and tidal friction, and primordial heat from the origin of the earth.
This energy due to geothermal gradients and heat flow from within induces diastrophism and volcanism in the lithosphere.
Due to variations in geothermal gradients and heat flow from within, crustal thickness, and strength, the action of endogenic forces is not uniform and hence the tectonically controlled original crustal surface is uneven.
Diastrophism and Volcanism are endogenic geomorphic processes. All processes that move, elevate or build up portions of the earth’s crust come under diastrophism. They include:
(i) orogenic processes involving mountain building through severe folding and affecting long and narrow belts of the earth’s crust;
(ii) epeirogeny processes involving the uplift or warping of large parts of the earth’s crust.
(iii) earthquakes involving local relatively minor movements.
(iv) plate tectonics involving horizontal movements of crustal plates.
Volcanism includes the movement of molten rock (magma) onto or toward the earth’s surface and also the formation of many intrusive and extrusive volcanic forms. Exogenic forces wear down (erode) relief/ elevations and fill up (aggrade) basins/depressions. When Earth’s surface erodes, the phenomenon is called gradation. Exogenic forces are generally land-wearing forces. Weathering, mass wasting, erosion, and deposition are exogenic processes.
Natural elements (like ice, water, and wind) along with Temperature, Precipitation, and celestial bodies (like comets and meteorites) are some examples of exogenic elements. They are capable of changing the configuration of the Earth’s surface and hence are called geomorphic agents. Gravity is a major component of exogenic forces as it facilitates downslope movement thereby activating waves and tides to induce currents and winds.

Question 8 of 35
8. Question
Consider the following statements regarding the Himalayan Fold Mountains:
- They are the oldest mountain ranges in the world.
- They are located in regions of high seismic activity and convergent plate boundaries.
- They are formed generally by sedimentary rocks and contain fossils that are marine in nature.
How many of the above statements are correct?
Correct
Solution (b)
Statement 1 Statement 2 Statement 3 Incorrect Correct Correct The Himalayan Mountains and the Alps are young fold mountains with rugged relief and high conical peaks. The Himalayas were formed as a result of the collision between the Indian Plate and the Eurasian Plate. Because of the impact of convectional currents, the crust was split into many pieces. The Indo–Australian plate got separated from the Gondwanaland and drifted towards the north.
They are located in regions of high seismic activity because they are formed out of plate movements. The Eurasian and Indian plates are continuously converging from millions of years. As it drifted towards the north, it collided with the Eurasian plate. As a result of this collision, the sedimentary rocks which were settled in the large-scale depression in the Earth’s crust called Tethys were folded and formed the Himalayas. They are formed generally by sedimentary rocks and contain fossils that are marine in nature. Incorrect

Question 9 of 35
9. Question
Fold Mountains are formed by the large-scale lithospheric movements in the earth’s crust. In this context identify the factors which lead to the formation of Fold Mountains?
- Faulting of the lithospheric crust.
- Convection flow movements in the Mantle.
- Magmatic intrusions into the crust.
How many of the above statements are correct?
Correct
Solution (b)
Statement 1 Statement 2 Statement 3 Incorrect Correct Correct Fold Mountains are by far the most widespread and also important. They are caused by large-scale lithospheric movements. They are a result of folding and not faulting. Faulting leads to formation of block mountains. Fold Mountains are created where two or more of Earth’s tectonic plates are pushed together. At these colliding, compressing boundaries, rocks and debris are warped and folded into rocky outcrops, hills, mountains, and entire mountain ranges. Fold Mountains are created through a process called orogeny. An orogenic event takes millions of years to create a fold mountain
Fold Mountains occur when two tectonic plates collide at a convergent plate boundary, causing the crust to over thicken. This process forces the less dense crust to float on top of the denser mantle rocks – with the material being forced upwards to form hills, plateaus, or mountains – while a greater volume of material is forced downward into the mantle Incorrect

Question 10 of 35
10. Question
Consider the following statements concerning the types of Volcanoes
- Shield volcanoes are mostly made up of basalt and low viscous lava thus covering larger areas.
- Composite volcanoes are characterised by eruptions of cooler and more viscous lavas than basalt.
- Caldera volcanoes are the most explosive of the earth’s volcanoes, thus altering the environment of the surrounding area.
How many of the above statements are correct?
Correct
Solution (c)
Statement 1 Statement 2 Statement 3 Correct Correct Correct Shield volcanoes are the largest of all the volcanoes on the earth. They are mostly made up of basalt and low viscous lava thus covering larger areas
The Hawaiian volcanoes are the most famous example. These volcanoes are mostly made up of basalt, a type of lava that is very fluid when erupted.
For this reason, these volcanoes do not erupt These are formed by lava flows of low viscosity. These volcanoes are not steep. They become explosive if somehow water gets into the vent; otherwise, they are less explosive.
Composite volcanoes are characterized by the eruption of cooler and most viscous lavas than basalt. These volcanoes often result in explosive eruptions. Along with lava, large quantities of pyroclastic materials and ashes find their way to the ground. They are usually found at the destructive plate margins. They have steep sides along with composite layers. Caldera volcanoes are the most explosive on the earth’s surface affect the surrounding environment. They are usually so explosive that when they erupt they tend to collapse on themselves rather than building any structure. After the eruption of magma has ceased, the crater frequently turns into a lake at a later time. This lake is called a ‘caldera’. Examples: Lonar in Maharashtra and Krakatao in Indonesia. Incorrect

Question 11 of 35
11. Question
Consider the following statements regarding Sea Floor Spreading
- It occurs at convergent plate boundaries only.
- It provides a supportive explanation for the Continental Drift theory.
- Alfred Wegner proposed that a new seafloor crust was continually formed at mid-ocean ridges.
How many of the above statements are correct?
Correct
Solution (a)
Statement 1 Statement 2 Statement 3 Incorrect Correct Incorrect Seafloor spreading occurs at divergent plate boundaries. Seafloor spreading is not consistent at all mid-ocean ridges. Slowly spreading ridges are the sites of tall, narrow underwater cliffs and mountains. Rapidly spreading ridges have much more gentle slopes.
Seafloor spreading disproves an early part of the theory of continental drift. Rather, Seafloor spreading helps explain continental drift in the theory of plate tectonics.
Seafloor spreading theory by Hary Hass played a pivotal role in the development of continental drift theory. It consolidated evidences presented by Alfred Wegener by disproving the tidal force and pole fleeing theory and furthering our understanding of the Formation of continents. It was Harry Hess who proposed the idea of Sea floor spreading and not Alfred Wegener. Incorrect

13. Question
Which of the following processes can be best associated with Diastrophism?
- Mountain building through severe folding of the earth’s crust.
- The heat generated by the radioactive elements in the earth’s interior.
- Weathering, mass wasting, erosion, and deposition.
How many of the above statements are correct?
Correct
Solution (b)
Statement 1 Statement 2 Statement 3 Correct Correct Incorrect Diastrophism, also called tectonism, large-scale deformation of Earth’s crust by natural processes, which leads to the formation of continents and ocean basins, mountain systems, plateaus, rift valleys, and other features by mechanisms such as lithospheric plate movement (that is, plate tectonics), volcanic loading, or folding. The heat generated by the radioactive elements in the earth’s interior leads to movements of Magma and tectonic activities. Diastrophism and volcanism are endogenic geomorphic processes. While Weathering, mass wasting, erosion, and deposition are exogenic geomorphic processes.

Question 14 of 35
14. Question
With reference to Hotspots, consider the following statements
- They occur at regions along the boundaries of Earth’s tectonic plates.
- A volcano above a hotspot continuously erupts and is active forever.
- Most hotspot volcanoes are basaltic
How many of the above statements are correct?
Correct
Solution (b)
Statement 1 Statement2 Statement 3 Correct Incorrect Correct A hot spot is an area on Earth over a mantle plume or an area under the rocky outer layer of Earth, called the crust, where magma is hotter than surrounding magma. The magma plume causes melting and thinning of the rocky crust and widespread volcanic activity. Hotspot volcanism is unique because it occurs at the boundaries of Earth’s tectonic plates, where all other volcanism occurs.
Hotspots can also develop beneath the continents also
A volcano above a hot spot does not erupt forever. Eventually, the movement of the tectonic plate carries the volcano off of its magma supply. Hence it is a temporary phenomenon. The best example of a hot spot volcanic chain is the Hawaiian Islands
Most of the Hotspot areas have basalt beneath them because the main source is Magma. Incorrect

Question 15 of 35
15. Question
Consider the following statements about Palaeomagnetism.
- Palaeomagnetism is the study of the record of the earth’s magnetic field with the help of magnetic fields recorded in rocks, sediment, or archaeological materials
- Magnetic minerals like Basalt align themselves in the direction of the magnetic field.
- This orientation is a demonstration of how geomagnetic reversals have happened over geological timescales.
How many of the above statements are correct?
Correct
Solution (c)
Statement 1 Statement 2 Statement 3 Correct Correct Correct Paleomagnetism is the study of the record of earth’s magnetic field with the help of magnetic fields recorded in rocks, sediment, or archaeological materials. The polarity of the Earth’s magnetic field and magnetic field reversals are thus detectable by studying the rocks of different ages.
Rocks formed from underwater volcanic activity are mainly basaltic (low silica, iron-rich) that makes up most of the ocean floor.
Basalt contains magnetic minerals, and as the rock is solidifying, these minerals align themselves in the direction of the magnetic field. This locks in a record of which way the magnetic field was positioned at the time.
Paleomagnetic studies of rocks have demonstrated that the orientation of the earth’s magnetic field has frequently alternated (geomagnetic reversal) over geologic time. Incorrect

Rocks formed from underwater volcanic activity are mainly basaltic (low silica, iron-rich) that makes up most of the ocean floor.
Basalt contains magnetic minerals, and as the rock is solidifying, these minerals align themselves in the direction of the magnetic field. This locks in a record of which way the magnetic field was positioned at the time.
Paleomagnetic studies of rocks have demonstrated that the orientation of the earth’s magnetic field has frequently alternated (geomagnetic reversal) over geologic time. -
Question 16 of 35
16. Question
Which of the following evidence supports the Continental Drift Theory?
- Matching of African and South American continents.
- Rocks of the same age across the oceans
- Absences of source rock in the region of rich placer deposits across continents.
- Distribution of fossils
How many of the above statements are correct?
Correct
Solution (d)
Statement 1 Statement 2 Statement 3 Statement 4 Correct Correct Correct Correct The shore life of Africa and South America facing each other have a remarkable and unmistakable match. A map produced using a computer program to find the best fit of the Atlantic margin was presented by Bullard in 1964.
The radiometric dating methods developed in the recent period have facilitated correlating the rock formation from different continents across the vast ocean. The occurrence of rich placer deposits of gold on the Ghana coast and the absolute absence of source rock in the region is an amazing fact. The gold-bearing veins are in Brazil and it is obvious that the gold deposits of Ghana are derived from the Brazil plateau when the two continents lay side by side. When identical species of plants and animals adapted to living on land or in freshwater are found on either side of the marine barriers, a problem arises regarding accounting for such distribution. The observations that Lemurs occur in India, Madagascar, and Africa led some to consider a contiguous landmass “Lemuria” linking these three landmasses. Mesosaurus was a small reptile adapted to shallow brackish water. The skeletons of these are found only in two localities: the Southern Cape province of South Africa and the Traver formations of Brazil. The two localities presently are 4,800 km apart with an ocean in between them. Incorrect

Question 18 of 35
18. Question
Consider the following landforms associated with Karst Topography:
- Uvalas
- Sinkholes
- Limestone Pavement
- Dolines
Arrange the above-given landforms in the correct sequence of their formation
Correct
Solution (b)
Erosional Landforms by Groundwater on the surface of the limestone are numerous shallow holes, which are small depressions carved out by solution where rainwater sinks into the limestone at a point of weakness. They are also known as sinkholes.
Once the water has sunk into the limestone, it etches out caverns and passages along joints or bedding planes. Where several swallow holes coalesce, a larger hollow is formed and is called a Doline.
Several Dolines may merge as a result of subsidence to form long, narrow to wide trenches called Valley sinks or Uvala.
Gradually, most of the surface of the limestone is eaten away by these pits and trenches, leaving it extremely irregular with a maze of points, grooves, and ridges or Ladies. Especially, these ridges or lapses form due to differential solution activity along parallel to sub-parallel joints. The lapie field may eventually turn into somewhat smooth limestone pavements.

A man inherits 4325 gold coins and divides them among his three sons viz. A, B and C in a certain ratio. Out of the total coins received by each of them, A donates 40 coins, B donates 20 and C donates 30 coins. Now, the ratio of coins left with them is 41:34:46. How many coins are with A now?
Correct
Solution (d)
Let the coins with A, B and C after they have donated be 41x, 34x and 46x respectively.
Total coins with A before donation = 41x + 40
Total coins with B before donation = 34x + 20
Total coins with C before donation = 46x + 30.
Total coins with the father = 4325
So, 41x + 40 + 34x + 20 + 46x + 30 = 4325 Or 121x = 4235 Or x = 35.
Coins with A now = 41x = 1435

Question 33 of 35
33. Question
In a race of 100 m, A beats B by 19 m and beats C by 10 m. By how many meters would C beat B in another 100 m race assuming C and B run with their respective speeds as in the earlier race?
Correct
Solution (b)
A beats B by 19 m in the 100 m race.
Thus when A completes 100 m, B only completes 81 m. again, A beats C by 10 m in 100 m race. Thus when A completes 100 m, C only completes 90 m.
Time taken by A to complete 100 m = time taken by B to complete 81 m = time taken by C to complete 90 m.
Let the time taken by B to complete 81 m = 10 seconds then C will also complete 90 m in 10 seconds
Speed of C = distance covered by C time taken = 90/10 = 9 m/s
Speed of B = distance covered by B time taken = 81/10 = 8.1 m/s
Time taken by C to run 100 m = distance to cover speed = 100/9 = 100/9 seconds
Distance covered by B in 10 seconds = speed of B x time taken = 8.1 x (100/9) = 90 m
∴ In the second race, C beats B by 10 m or When A covers 100 m, B can cover 81 m and C can cover 90 m.
When B covers 81 m, C can cover 90 m.
When B covers X m, C can cover 100 m ratio of distance covered by B and C in same time will be same
Thus, 81/90 = X/100 ->X = (81 x 100)/90 = 90 m
∴In a hundred meter race, B beats C by 10 m.
Incorrect
Solution (b)
A beats B by 19 m in the 100 m race.
Thus when A completes 100 m, B only completes 81 m. again, A beats C by 10 m in 100 m race. Thus when A completes 100 m, C only completes 90 m.
Time taken by A to complete 100 m = time taken by B to complete 81 m = time taken by C to complete 90 m.
Let the time taken by B to complete 81 m = 10 seconds then C will also complete 90 m in 10 seconds
Speed of C = distance covered by C time taken = 90/10 = 9 m/s
Speed of B = distance covered by B time taken = 81/10 = 8.1 m/s
Time taken by C to run 100 m = distance to cover speed = 100/9 = 100/9 seconds
Distance covered by B in 10 seconds = speed of B x time taken = 8.1 x (100/9) = 90 m
∴ In the second race, C beats B by 10 m or When A covers 100 m, B can cover 81 m and C can cover 90 m.
When B covers 81 m, C can cover 90 m.
When B covers X m, C can cover 100 m ratio of distance covered by B and C in same time will be same
Thus, 81/90 = X/100 ->X = (81 x 100)/90 = 90 m
∴In a hundred meter race, B beats C by 10 m.

Question 34 of 35
34. Question
When in each box 5 or 6 dozens of apples were packed, three dozens were left. Therefore, bigger boxes were taken to pack 8 or 9 dozens of apples. However, still three dozens of apples remained. What was the least number of dozens of apples to be packed?
Correct
Solution (b)
Required number of apples = (LCM of 5, 6, 8, 9) + 3 LCM of 5, 6, 8, 9 is
From above calculation, LCM = 2 x 3 x 5 x 4 x 3 = 360 Hence, required numbers of apples in dozens = 360 + 3 = 363 dozens.

Question 35 of 35
35. Question
Suman, a mathematician, divides Rs. 60 among his two sons in such a way that the sum of the reciprocal of the amounts received by sons is 3/25. What amount did the son who got the higher amount receive?
Correct
Solution (a)
Let the amounts received the two sons be Rs. x and (60 –x) respectively.
According to the question,
1/x + 1/(60-x) = 3/25
Or 25 × 60 = 3x (60- x)
Or 25 × 20 = x (60-x)
Or 50 × 10 = x(60-x)
This equation satisfies for the values 50 and 10. So, the son who got higher amount received Rs. 50.
Hence, option (a) is the correct answer.
